If I have two fields regarding orders - one called Plastic Orders, one called vinyl Orders. I do want to keep them separate most of the time, however when I want to select all orders, how do I do this with?

so the data comes in like this:

PO VO

2 10

3 12

6 15

but I want to be able to click on a button??? that would enable someone to select Orders and total orders or PO and VO woulld show.
